When I switched off basement room receptacles circuit breaker while
all others except sub-panel which does not seem to affect the
problem were on we found there is 8 V power in that circuit.
Switching off some of other circuits reducing this voltage to about
2 V and only switching off all new circuits brings disconnected
voltage to zero as it should be.
If you were reading this voltage at the recept with nothing
plugged in
on that circuit, then the 8V is perfectly normal reading and is
due to
stray coupling between conductors.
8V seems high. I rarely see more than a few hundred mV from
inductive coupling alone.
Really? I've often seen over 50 VAC, and still with a load as small
as a 7 watt night light, it went down to zero VAC.
Something doesn't jive here. The voltage shouldn't go to zero unless
you short circuit the wires. Any light has resistance and any
resistance that has current flowing through it will have a voltage
across it. The only way the voltage can be zero with current flowing is
if the resistance is also zero (a dead short - with a very short piece
of wire!).
Are we mixed up again? I thought we were talking about inductive
coupling, not a transformer. To keep it in layman's terms, "the voltage
ain't got no balls" or *amperage* to back it up. So the slightest load
across the outlet will bring it to zero VAC, (close enough for this
forum anyway). I've even simply touched across the two meter leads by
accident, with no other load on the circuit, and the voltage went from
close to 50VAC to below 1 volt. Remember, this is with the circuit off
of course, and inductive coupling, not a short or an open neutral, and
me as the only load, even with sweaty hands, still probably over 10K ohms.
How are you measuring the voltage? Across what terminals?
In the outlet, from hot to neutral, with the night light in the other
socket of the same outlet.
